Tomasz’s Burson Playmate 2 with M-Audio BX8 D2 and Fostex TH610

• Impedance: 25 Ω
• Sensitivity: 98 dB/mW ≈ 114.0 dB/V (calc.)
• Frequency response: 5 Hz – 45 kHz
• Plugs / cables supplied: 3 m Y-cable, detachable 2-pin; 6.3 mm plug
• Other: max input 1,800 mW; approx. 375 g without cable

Matching notes: At 25 Ω and 98 dB/mW, the TH-610 is a low-impedance load: about 0.63 V (16 mW, 25 mA) for 110 dB SPL (calc.). Burson does not publish a 25 Ω rating for the Playmate 2. Its 16 Ω and 32 Ω ratings (3.5 W SE; 2.5 W SE) fall either side of it. The Playmate 2’s under 2 Ω headphone output impedance is less than 1/12 of the load. ^{[1] [2] [3] [4]}
